Join Scott Onstott for an in-depth discussion in this video Revolving profiles and manipulating layers, part of AutoCAD: 3D Surface Model Design.
- Our next project is to model the bicycle tire and rim.…I'm going to orbit around and…get a view of this cross-section over here.…Let's reset the UCS back to world.…You can do that by typing UCS, enter, enter.…So this cross-section is in the wrong plane.…Right now it is flat on the ground.…We need to rotate it so that it's…going in the right direction.…I need to rotate it around an axis running this way.…So I'd like to draw that axis in and before I…get drawing, I'm going to create a new layer or two.…
I'll make a new layer called 3-D tire…and another one called 3-D rim.…For the tire, unlike all of the other objects,…I'm actually going to choose a color…which is similar to the tire itself.…I'm not going to choose pure black,…but I'll choose this very dark gray, color 251.…I'll set that layer current and…I'll leave the 3-D rim layer white.…I'll draw a line from the quadrant here…straight through, so this represents the axis…that I'd like to pivot these objects on.…
In order to rotate them, I am going…to have to get the z-axis to be…
